OP It’s hard if you don’t eat any herbs or spices as the reality is they make a lot of healthy food more palatable.
Try making some good dressings, white balsamic vinegar, oil, mustard honey and seasoning is a really light and tasty dressing.
You can also make yoghurt based dressings, if you can tolerate mint then a yoghurt and mint dressing is delicious.
A good homemade pesto is easy and can add interest to bland dishes, if you have a food processor then walnuts, spinach, oil and Parmesan make a really easy pesto.
It will freeze or live in the fridge for a week or so, delicious on chicken and fish.
Bulgar wheat and couscous are a good base instead of potato and rice and work well with roasted vegetables.
Bulgar can also be used in risotto.
A wholemeal tortilla wrap in a good oven pan topped with, eggs, cheese, tomatoes etc then baked in the oven makes a fabulous frittata type lunch.
Poke bowls are a favourite of mine, lots of ideas on line but a few chickpeas, finely chopped salad ingredients, hummus, raw veg, avocado and a lovely dressing topped with chicken, fish, grilled aubergine and a sprinkle of seeds.
I make sourdough and love it topped with plain grilled tomatoes, devilled mushrooms or beans (homemade baked beans are easy)
Regarding the poster with lots of chickpeas, they purée well into soup.
I made a big batch of Moroccan carrot and chickpea soup last week it was really hearty.
Keep it up you will feel the benefits, honestly what a bit of junk food does to my husbands gut is dreadful, a packet of cheddars🤮and a Cooplands bacon butty and he’s moaning for 48hours!
I have encouraged him to keep a food diary and it’s beginning to dawn on him.
